I'll try to avoid heavy PK areas without being somewhat "ready". Ready doesn't necessarily mean having nether up, but it means knowing I can put it up. I'll try to avoid eastern without at least fly or nether ready.

If you've used it recently, and know you have a lot of conflict coming, retreat to a non-obvious graveyard (not galadon), or one in a city where there's a trib on duty (hamsah).

Some of the things that'll make you effective as a necro will make you effective as a pker in general. I've read your logs and you're good at being the agressor. So in those instances when you're not, you need to do a real quick evaluation to determine if you can stay in the fight:
-Do I have fly available
-Do I have any DR available (nether, shield from a wand, even desensatize or protection against a goodie)
-Do I have any army
-Can I sleep this char

Use those as criteria to figure out when you have a shot at winning
